I'm following this thread. I noticed that a little on my left ramp flap after I put it back together. My bigger problem is after shopping my scared stiff and waxing and rebuilding flippers is that now sometimes when I head to the right ramp on a ball moving fast through the inlane it flies up out of the ramp into the bumper area. Never had that problem before shopping it and it doesn't look like the right ramp had a plastic on it to keep the ball in the ramp.
